Description:

Fieldbus is a two-way digital communication system. It is a revolutionary technology for configuring instrumentation control systems and a promising successor to the standard 4 to 20mA analog communication used in most field instruments today. By combining Fieldbus communications with digitalYEWFLO's ability to simultaneously output analog and pulse readings for flowrate, temperature, mass flowrate and total flowrate, a greater variety of powerful flow control applications are possible.……

digitalYEWFLO Fieldbus Type Vortex Flowmeter

Yokogawa’s proprietary filter (SSP) for digital signal processing analyzes vortex signals and automatically selects the optimum settings for the best possible measurement.

Features: digitalYEWFLO Fieldbus Type Vortex Flowmeter

-	Interoperability (ITK 5.0.1)
	FOUNDATION fieldbus specifications (ITK 5.0.1) grant the interoperability of the field instruments.

-	Reduction of instrumentation cost
	The multi-drop wiring on the Fieldbus communication line contributes to the reduction of wiring cost.

-	Mass flow calculation
	Arithmetic (AR) function block expands the mass flow calculation function for the saturated steam, superheated steam and gases by using external pressure/temperature input (/MV:internal temperature input) with a high accuracy. Additionally, in combination with FlowNavigator Flow Configuration Software (FSA120) brings to the high accurate mass flow calculation output, ex. natural gas process, physical properties database for 126 fluids and custom fluids.

-	User-friendliness
	The common function block of field devices have the same operability, because of their common specification. The individual device setting (Transducer Block parameter setting) can be done simply by executing METHOD.

-	Independent flow and temperature calculations (multi-variable type: option)
	The multi-variable type (/MV: option) of digitalYEWFLO separately outputs flowrate output (AI1) and temperature output (AI2) . Two DI function blocks output the limit signal output both flowrate and temperature.

-	Advanced self-diagnostics
	The digitalYEWFLO has advanced self-diagnostics which can predict and identify anomalies in the process conditions, such as high pipeline vibration and abnormal flow. Also, the Fieldbus type digitalYEWFLO supports various alarm functions, such as high/low-limit alarms and alerts of block errors, based on the FOUNDATION fieldbus specification.

-	Link Master function : BASIC at factory setting.
	digitalYEWFLO Fieldbus models support the Link Master function. This function enables backup of network manager and local control only by field devices.

-	PID function block (option)
	A PID function block (with the I-PD control algorithm) enables the field device to control the process.

-	Software download function (option)
	Software download function permits to update DY software via a FOUNDATION fieldbus. Typical use of this function is to add new features such as function blocks and diagnostics to existing devices.
